Question

Calculate the present of carbon, hydrogen and oxygen in ethanol (c2h5oh)

Answer 1

Answer:

We have to us the concept of mass % to find the presence of carbon, hydrogen and oxygen in ethanol (c2h5oh).

$mass \: \% = given \: mass \: \div \: total \: mass \: \times \: 100$

Explanation:

Mass % of carbon = 24/46

Mass % of H2 = 6/46

Mass % of o2 = 16/46
